Application filed August 19, 1911. Serial No. 644,989.

'To all 'whom it may concern:

Be it known that l, CHARLES M. BREN- `NER, a 4citizen of the United States, and a resident of Shreveport, in the parish of- Caddo and State of Louisiana, have invented a new -and Improved Valve-Float for Closet-Tanks, of which the following is a full, clear, and exact description.

My invention'relates to a valvefloat and is more particularly adapted for y closet tanks.

15in object of my invention is to provide a new and improved float" which is simple in construction, and positive in its action.

A further object of my invention is to provide a float which will have not only the permanent air chamber common to'devices of .this character, but in 'addition have a water-sealed air pocket.

l attain the above-outlinedobjects by disposing a bell-shaped member within a substantially semi-spherical member, fastening them together to form between said members a permanent air chamber, the open end common to both'members normally facing downward to be closed by the water rising in the "tank, to form an additional al1-fS pocket.

With theabove and other objects in view, as will more fully hereinafter appear, the present invention 'consists in certain novel .details of construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and more particularly pointed out in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the-figures, and in which- Figure 1 is a perspective view showing a preferred embodiment of my invention; and F ig. 2 is an enlarged vertical transverse section taken through the device shown in Fig. 1.

Described more in detail, there is shown a substantially semi-spherical outer member 3, disposed within which member is a bellshaped member 4 ofl less depth than the outer member to form between said members, a permanent air chamber 5. The meeting sides 'of the two members are in contact for some material distance and the edges are bent inward and then back upon themselves, to form a lock seam 'i'. It will be seen that this renders the air chamber 5 hermetically sealed.

member is a brass plate 8 coacting with a vsimilar plate 9 on the outside of the outer member, to brace the two sides together and to reinforce the float at this point. The

' outer plate'9 carries an internally-threaded socket 10 or other similar member to which the float rod 1l is attached by any suitable means. If desired, similar reinforcing brass plates 12 may be disposed on the outside and the inside of the meeting sides 6, to further reinforce the ioat, and these additional plates may be disposed on the diametrically opposite sides from the plate 8, or at any other suitable point about the sides 6.

It will be understood that this float is ward into the closed tank.v so that the rising water in the tank, as the latter is illed, will close the opening 13, forming a water-sealed air pocket 14 within the bell-shaped member. This water pocket will aord a buoyancy to the float in addition to the buoyancy afforded by the permanent'air space 5, so that with the same amount of material, a greater buoyancy is effected by means of my 'improvedfloat than by the ioats now in common use. s

While a preferred embodiment of the invention has been' described, it is to be understood that many changes could be made in the above construction and many apparently widely different embodiments o ii this invention could be made without departing fromthe scope thereof. It is intended that all matters contained in the above description or shown in 'the accompanying drawnot in a limiting-sense. It is also to be understood that the language used in the following claims is intended to cover the full scope of the invention and is not to be given any narrower construction than the prior relativities of. parts are non-essential, except as called for in the claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

ning a substantially semi-spherical member, anda bell-shaped member dlsposed within the semi-spherical member, both of said ings, shall be interpreted as illustrative and l. A valve float for closet tanks, compris'-l Disposed Qn the inside of the bell-shaped mounted with its open end 13 facing downart'demands, and that materials, sizes and members having their open ends facing* in the seme direction, both of sind members being lmperfornte 'and the inner member v havingva curved top and an approximately cylindrical body portion the outer face of which, frein its open end approximately throughout its height, engagesthe corresponding inner face of the semi'- spherical member, the said members being fastened together at their open ends and the inner vmember being of less depth than the outer inernber'to form between them a hermetically lsea-led air chamber, the open end of the float facing downward and adapted to engage the water in the tank to form a. closed .Water-sealed air pocket in said inner member, co-acting; reinforcing' members disposed respectively on the inside of the inner member and the outside of the outer member at the meeting sides of said members, und a Hoet Im connected with one of the :reinforcing members.

2. A valve float for closet tanks, comprisingV a pair of hollow'imperforate members each having an open end, one of said memmembers a permanentlv sealed air chamber,

and to reinforce the said members at their open ends, the open end of the oat being adapted to be closed Vby the Water in the tank to form a closed Water-sealed air pocket insa'id inner member, plates disposed respectively on the inside of the inner member andthe outside of the outer member at the meet-ing sides of said members to reinforce the same, and a float stem connect# ed withl one of the outer plates.

In testimony whereof l have signed my neme to this specification in the presence of two subscnbing Witnesses.

l CHARLES M. BRENNER.
